Summary
University of California, Office of the President
education university research legacy
UCOP-ASN belongs to the University of California Office of the President — the system-wide administrative headquarters of the ten-campus UC system, not any one campus. RIS sees 19 IPv4 prefixes, 53,760 addresses, no IPv6, and 3 observed neighbours.
What it's used for
UCOP's own administration and the system-wide services it runs on behalf of all the campuses: central IT, business and financial systems, and the shared library and digital-collection infrastructure the office has operated for decades. The sampled reverse DNS, by05-mgmt-01.ucop.edu, is a management host in the office's own .edu zone — first-party naming that ties the announced space directly to the holder rather than to an upstream or a customer.
Notable
Every prefix sampled is registered to the University of California - Office of the President, but the netnames are the interesting part: most of 128.48.0.0/16 is registered as UCDLA-NET-B and one of the 192.35.x /24s as UCDLA-FE1NET. UCDLA is an internal departmental code from UC's long-running library-automation and digital-library work, not a separate organisation. This is the classic case where the handle names nobody — read the org: field, which is UCOP throughout, and the apparent third-party registrant evaporates.
Interesting
Three observed neighbours against nearly 54,000 addresses is a research-and-education shape: a large institution that reaches the internet through a small number of upstreams (in the UC system's case, regional and national R&E networks) rather than peering broadly. Note also that this is an administrative network — classifying it as education is right because of what the organisation is and what the .edu space carries, but do not expect campus dormitory or student-residential traffic here. And the absence of announced IPv6 is a genuine gap for an institution of this size.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,845 prefixes, as published 2026-10-31. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
